According to a 10-K financial report filed earlier today, it appears that Interplay - who were supposed to have been developing a Fallout MMO - might instead lose the Fallout rights for the game.

The looming action (which has not yet been made official, but is still likely enough to warrant Interplay filing about it) stems not from the game's rights - which Interplay picked up fair and square - but from the game's progress. Or lack thereof.
